To all whom it may concern:

Be it known that I, O'r'ro THIEME, a citizen of the United States,residing at the city of St. Louis, State of Missouri, have invented acertain new and useful Improvement in Type-Guards, of which thefollowing is a full, clear, and exact description, such as will enableothers skilled in the art to which it appertans to make and use thesame, reference being had to the accompanying` drawings, forming partofdthis specification, in which- Figure 1 is a side elevational viewthrough therear end of a calculatingr machine showing my improved typeguard in position thereon.

Fig. 2 is a vertical sectional view through the same.

Fig. 3 is a horizontal sectional view through the same.

Fig. 4 is a side elevational view of the printing segments detached.

Fig. 5 is a detail view partly in section ofthe inking ribbon guide forthe printing segments.

Fig. 6 is a front elevational view of the ty e segments. This inventionrelates to a new and useful improvement in type guards for printing typeof calculating machines, and is a division of an application led by meMay 2.0, 1916, Serial Number 98,853.

yIn the parent case there is illustrated and described a tally rollattachment for the Moon-Hopkins billing` machine including in itsstructure denominational racks 100 which u cooperate with registerwheels 119 and 268. Type segments 561 mesh with the rear ends of theseracks for the purpose of making a printing1 impression upon the tallyroll` strip 600 carried by the laterally adjustable frame 503 which,when vibrated, causes its platen to press the paper against the inkingYribbon in the printing line and eiiect a printing impression from thetally roll segments. The. record thus made may be of the items or of thetotals indicated the register wheels H9 or 268.

Means are also shown in the parent case for laterally adjusting theirame 503 wherehy the records made on the tally strip may be arrangedincoiunn:l order.

Means are also disclosed n the 5% enecting the feed of the tally rollstrip, returning the frame 503 to its normal or starting position, andcontrolling the several operations of the frame 503 automatically byadjustable stops on the main paper carriage identified with thewords-printing mechanism of the typewriting mechanism, not herein shown.These form no part of my present invention, as this application isconiined'to the construction and method of operation of the type guardswhich coperate with the tally roll printing segments.

As the platen 505 carried by the vibrating frame 503 extends entirelyacross the printing line in any lateral position of the frame 503, andas the zero printi type on the segments 561 are normally in t e printingline, it follows that some means must be provided to prevent theprinting of zero `type to the left of any number recorded, and

Whenever the denominational racks 100 are moved forward, they positionthe segments 561 so as to present appropriate printing type in theprinting line, and if after said type are so positioned, the frame 503is vibrated so as 'to cause the tally roll strip 600 to be pressedagainst the inking ribbon arranged 'bove the type, a printing impressionwill be made, all as described in said parent ense.

Each of the type 'segments 561 carries printing type 562 on itsperiphery, and each of said printing segments in addition is providedwith a shoulder 563 on its hub. 564 indicates a rocking "iP-shapedlever, there being one ci such levers for each printing segment. eac ilever 'being independently held rearwardly against a stop ha? 5G @a hymeans of a spring 565. 'The rearward extension or shoulder ci thisT-sharmd lever 5de is thus cm=ed to bear against the shoulder 563 on'the hui ot the printing segments.

per

the type 562, the rear or free end of said guard being bent upwardly soas to Provide a space overthe zero type for the inking ribbon 60021.Whenever the racks 100 move forwardly, they will cause the printingsegments 561 to be rocked rearwardly, and consequently the zero of eachoperated segment will be moved rearwardly below the inking ribbon so asto successively bring printing characters 1, 2, 3, 4, etc., opposite theprinting line. Upon the initial rearward movement of the segments 561,the shoulder 563 will rock the "shaped lever 564 forwardly, thuscarrying with it the guard plate 566 which will uncover the type in theprinting line in readiness to receivethe impression stroke of theplaten. Each one of the T- shaped levers 564 is provided with a bentportion 567 see Fig. 6) which extends behind the neXt adjacent T-leverof lower order so that when' a segment 561 of any higher order isoperated, notwithstanding the fact that the racks 100 of lower order arenot operated, the T-shaped levers identified with the printing segmentsin the lower orders will be rocked forwardly by means of theseprojections 567 so that the zero type in the printing iine in such lowerorders will be exposed to maire a printing impression. The guards overthe Zero type in the higher orders above the highest digit in the numberbeing recorded, will not be moved, and consequently, will bind the zerotype in such higher orders. When the type have been brought to theprinting line and a printing impression is made, the restoration of theracks will cause the printing seg-i ments to be returned to their normalor home position in which the zero type are in the printing line. Inorder to avoid excess movement of the T-shaped levers 564, the hubs'oi"the printing segments below the shoulders 563 preferably formedconcentric so that after the 197 type has been positioned to theprinting line, the successive movement the segments in bringing the 2 3and 4 typeto the printing line, will cause the rear end of the T-shapedlever to ride on the concentric portion of the hub, and thus the typeguard in exposing the type the printing linel will not be given anexcess unnecessary forward movement. @i course when the segment isrestored and 'the "nub- 563 passes beneath the rearward extension of theclm-shaped lever, said 'lshaped lever will move rearwardly untilarrested by the bar 564g, in which position the type guard will cov thezero type.

As shown 5 and 6, there is a ribbon guide 616, there being one of saidribbon -guides arranged at each side of the printing type so as to guidethe ribbon over the printing line, z'. e., the line in which the zerotype are normally in printing position. These ribbon guides are mountedon ends of naeaevi plates having slot and pin connection with arms 617and are normally held outwardly by means of springs 618 so that when theplaten makes a printing impression, these guides will yield slightly andthen lift the inking ribbon away from the printing type so as to permittheir free restoration and at the same time enable the inking ribbon toremain in its printing line position. I have not herein disclosed anymeans :for

'feeding the inking ribbon, as the same is sot forth in the parent casebefore mentioned.

What I claim is:

1. In an apparatus of the character described, the combination ofdenominational type segments whose zero type are normally in theprinting line, a type guard normally covering said zero type, and meansfor moving said type guard upon the actuation of its companion segmentwhereby the type positioned in the printing line will be uncovered.

2. In an apparatus of the character described, the combination ofdenominational printing segments whose zero type are normally in theprintin line, exible type guards which norma ly cover said zero printingtype, and means operated by said `type segments whereby said type guardsare moved to uncover the type in the printing line of the actuatedsegment.

3. In an apparatus of the character described, the combination ofdenominational printing segments whose zero type are normally in theprinting line, iiexible type guards which normally cover said zeroprinting type, means operated by said type segments whereby said typeguards are moved to uncover the type in the printing of the actuatedsegment, and connections between the said type guards whereby the zerotype to the right of any actuated segment will be exposed.

4. In an apparatus of the character de' scribed, the combination ofdenominational printing segments whose zero type are normally in theprinting line, exible type guards which normally cover said zero type,yielding ribbon guides for supporting au inking ribbon between said zerotype and said type guards, means for retracting said type guards touncover said ribbon and expose the type in the printing line, and aplaten for ed'ecting a printing impression on a strip of paper over theexposed type only.

5. The combination with a rocking printing segment, of a type guardholder normally in engagement therewith so as to cover the type on theprinting line, and means whereby when the digits on said segment aremoved to printing osition in one direction., said type guard wi l bemoved in the opposite direction to expose the type on the printingline..

6. The combination of a Erinting segment having a projection, a roe ingtype guard support coperating with said projection and movable in anopposite direction to the movement of said printing segment when thelatter is moved, and a type guard carried by said support, the free endof Which is normally located over the type in the printing line.

7. The combination of a printing segment having a. shouldered hubportion and a spring-pressed type guard support coperat-ing therewith,and a type guard carried by said support.

8. The combination o f independently operated denominational typesegments, guard supports operated thereby, there being one of saidsupports for each of said segments, and Hexible type guards carried bysaid support, the free ends of which normally cover the type in theprinting line, means whereby said type guard supports are actuated touncover the type in the printing line whenever its companion typesegment is operated, and means whereby said type uard supports may beoperated independently of any movement of said type segments.

In testimony whereo` I hereunto aiix my signature this 21st day ofMarch, 1918.
